Application filed April 19,

To all whom may concern Be it known that 1, JOHN C. STnrxnnnucn, a citizen of the United States, residing at Mandan, in the county of Morton and State of North Dakota, have invented new and useful improvements in Packing-Rings, of

1 "which the following is a specification.

This invention relates to improvements in packing rings and has particular application to what might be termed a compensat ing packing ring. I

in carrying out the present invention, it is my purpose to provide a packing ring which will'be found especially useful in conjunction with piston rods and the like for effecting a fluid tight joint. between the cylinder and the rod and which will be con-- structed in such manner that any wear on the ring will be automatically taken up or compensated fort-hereby preserving the life and efiiciency of the ring as an entirety.

It is also my purpose to provide a packing ring" which will embody in its construction a number of sets of curved strips disposed in ring or circular formation and arranged or correlated in suchmanner as to be capable of relative movement in the event of wear on the ring whereby the life of the ring will be preserved and the efficiency of the joint maintained.

Furthermore, I aim. to provide a compeneating packing ring which will, embrace the desired features of simplicity, efficiency and durability and which may be readily assembled and disassembled for application and removal and wherein the component parts will be arranged in such relation as to automatically take up any wear.

With the above and other objects in view, the invention consists in the construction, combination and arrangementof parts hereinafter setforth in and falling within the scope of the claim.

In the accompanying drawing, Figure l is a perspective view of a packing ring constructed in accordance with my present invention. Fig. 2 is a cross sectional view through the ring. Fig. 3 is a perspective View of a modified form of ring, and Fig. 4- is a cross sectional view through the form of ring illustrated. in Fig. 3.

Referring now to the accompanying drawing in detail and particularly to the form of my invention illustrated in Figs. 1 and 2, the numerals l, 1 designate a set of curved Sp'ecificatiozrof Letters Patent.

strips constructed of any suitable material and each having formed integral with the inner face thereof a pair of inwardly extending overlamiing lugs 2, 2, the opposite ends of each lugbeing cut out toform a straight edge 3 contiguous the inner face of the respective strip, and a downwardly and outwardly inclined edge 4 contiguous the straight edge. These curved strips 1, 1 are designed to be disposed in ring orcircular formation as illustrated in Fig. 1 of, the

at the opposite end. These tongues are placed in face to face contact with the free portions of the overlapping lugs 2, 2 and the tongues with the second respective strips abut the lower end of the downwardly and outwardly inclined edges 4. The outer surfaces of the curved strips 1, l are formed with alining longitudinally disposed grooves 7, 7 designed to receive a coiled contractile spring 8, or other suitable form of tension acting to hold the various strips in ring or circular formation about the shaft or rod.

From the foregoing description taken in connection with the form of my invention illustrated in Figs. 1 and 2-of the drawing, it will be seen'that when the sets of curved the shoulders formed at the junction of the tongues 6, 6 with the respective strips 5, 5 will abut the lower ends of the downwardly and outwardly inclined edges 4: of the strips L 1, while the spring 8 will act to hold such shoulders in snug engagement with the adfacebf the ring, formed of the parts just tion of the rod or shattwithin the ring, it

will be seen that the pring will-draw the various curved strips togethersoj a's to'compensate the fall or take up the weafl bh the parts.

drawing and have the confronting ends thereof spaced apart, while a second set of I in a plane parallel with that of the tongue strips are assembled as illustrated in Fig 1,

jacent ends of the lug. Now, as the inner' described, wears away, incident to themoshoulders, formed at the junction of the or take-up device encircling the strips and.

In the construction illustrated in Figs. 3 and l, the overlapping lugs 2, 2 on each curved strip 1 are spaced apart and interposed between such lugs is a web 9 having the opposite ends thereof projecting beyond the lugs as at 10, while the curved strips 5, 5 of each set are spaced apart by means of a web 11 and have the ends thereof opposite from the tongues extended beyond the web as at 12 and cooperate with the confronting portions of the tongues to form slots 13 adapted to receive the projecting ends 10 of the webs 9. i

From the above description and various forms of the invention delineated on the drawing, the construction, mode of operation and manner of employing my improved packing ring will be readily apparent. It will be seen that I have provided a packingring whereby wear on the parts thereof is automatically taken up or compensated for, while the rim may be readily assembled and disassemble v While I have herein shown and described certain preferred forms of my invention by way of illustration, I desire to have it understood that I do not limit myself to the forms of my linvention herein described and delineated, as modification and variation may be made within the scope of the claim without departing'from the spirit of the invention.

I claim:

A packing ring comprising a set of curved strips disposed in circular formation, overlapping lugs formed on the inner side of each strip and each having the opposite ends thereof cut out to form a straight edge contiguous the inner face of the respective strip and downwardly and outwardly inclined edgecontiguous such straight edge, a second set of curved strips disposed between the first-mentioned strip and overlapped thereby, tongues projecting outwardly from the opposite ends of the last-mentioned strips and disposed in parallel planes and each forming with the respective end of the strip a shoulder and lying in face to face contact with the projecting ends of the adjacent lug on said first strip, and means surrounding said strips whereby the same may be moved relatively to one another to contract the ring.

In testimony whereof I aflix my signature in presence of two witnesses.
